I’m trying to set the battery bank size through the app for my BMV 712, but it won’t accept values greater than 999Ah. Any values above 999Ah reverts back to just 1Ah when tapping accept. Is this a bug or limitation of the app?
For background, I have 12x Lion UT 1300 batteries, each have 105Ah of capacity for a total of 1260Ah. They are wired 4s3p for an operating voltage of 48v.
Any help is greatly appreciated, thank you!
Edit: I didn't read the part with the 48V setup.
The usable capacity only increases in parallel, not in series.
So you have a capacity of 3x105Ah = 315Ah.
But it is still a good hint and I will forward it to the developers.
I just tested it with the demo library.
If you just type 999 it accepts the 999Ah, but if you type in 1260 it jumps to 1Ah.
You have to leave the "Ah" in the form and enter 1260Ah than it accepts 1260Ah.
Enter it like this:
not like that:
Your correct battery capacity for a 48V system for 4S3P x 105AH batteries is 3 x 105 = 315AH
I didn't read the part with the 48V setup.
The usable capacity only increases in parallel, not in series.
So the capacity is 3x105Ah = 315Ah.
You are correct, in my haste I mucked this up and I can't even do my maths right anyway! Corrected.
